SR4 - Mechwarrior, Mech Conversion rules Options

[The Jopp]

Ok, this is a giant brainfart so take it for what it is. I just cobbled together what might work to play Mechwarrior in SR4 (might work, might not). This is basically mech design and combat rules.

Shadowrun 4 – Mechwarrior Conversion Rules

1. Mech Weight Classes
00-19= Ultralight Mechs
20-35= Light Mechs
36-55= Medium Mechs
56-75= Heavy Mechs
76-100= Assault Mechs
101-135= Collosal Mechs

2. Mech Base Cost
100K / Ton

3. Heat Buildup Rules
All mechs have 100 Heat
Heat buildup is calculated by the following formula:
DV+AP= Heat

Example: Firing a heavy pistol would give 6 Heat.

4. Heat Reduction Rules
Gas Vents are now Heat Sinks
Cost: As Gas Vent
Size: As Gas Vent Model (Gas Vent 3 becomes Heat Sink 3 and takes up 3 Mod Slots)

5. Elemental Armors
Daihatsu Horseman is the base shell for making an Elemental like armor

6. Recoil
Only Vehicle Class Weapons give Mechs recoil.

7. Mech Speed
00-130= Ultralight Mechs
00-110= Light Mechs
00-90= Medium Mechs
00-70= Heavy Mechs
00-50= Assault Mechs
00-30= Collosal Mechs

Speed values are not absolute and can be modified with the Similar Models rule.

8. Mech Handling
+2: Ultralight
+1: Light
+0: Medium
-1: Heavy
-2: Assault
-3: Collosal

9. Mech Acceleration
30/ 50: Ultralight
25/ 45: Light
20/ 40: Medium
15/ 30: Heavy
10 / 20: Assault
05 / 10: Collossal

9. Mech Body Values
Weight in tones equal structure value of the mech. Each point must be distributed as a body value for the following locations:
Head
Left Arm (Can be left at 0 – The Mech class have no arms)
Right Arm (Can be left at 0 – The Mech class have no arms)
Front Torso
Rear Torso
Left leg
Right Leg

Example: Light Mech at 20 tonnes
Head : 2
Left Arm: 3
Right Arm: 3
Front Torso: 3
Rear Torso: 3
Left leg: 3
Right Leg: 3

10. Mech Damage
The mech have a damage track for each body part and damage will affect performance.
Equipment and weapons mounted in damaged limbs will have performance penalties and affect dicepools. Damages to Head (cockpit) will affect Sensor tests, damages to Legs will affect movement and handling.

11. Modification Slots
A Mech have a total amount of Modification Slots equal to Tonnage.

12. Mech Armor Value
A Mech starts with an armor value equal to half tonnage to distribute. Each individual limb can be increased by X2 body value with armor Mods.

13. Weapon Mounts
Each limb can have up to BOD value of weapon mounts but have only BOD amount of Mod Slots. Weapon mounts follow the base rules from SR4 so max 1 mount per 3 BOD.

14. Weapon Size Classes
All weapon in SR4 (Arsenal) are classified as Ultralight vehicle weapons. All weapons can be increased to the corresponding size class with the following formula:
Each increased size class adds +1DV -1AP Range +10% [Weapon Level X Weapon Cost] +1 Mod slot for each size class when installing a weapon mount.

Any Mech that installs an oversized weapon (Heavy weapon on a medium mech) require an additional mod slot for that weapon mount for each size difference.

An ultralight with an assault class weapon with the corresponding weapon size would have +4 Damage -4AP and +40% range but the size for the weapon would be 6 Slots
+1 Weapon Mount
+1 Oversized Weapon
+4 Assault Class Weapon


15. Heat Reduction
A mech has a base heat reduction equal to 1/10 of its weight. A 100 ton Mech would have heat reduction of 10 for each combat turn. Heat sinks add their rating to heat reduction.
